COMBINED SHAVING AND CLIPPING MACHINE.

Specification of Letters Patent.

Patented Sept. 7, 1915.

Application filed February 23, 1915. Serial No. 9,789.

To all whom it may concern Be it known that I, MICHAEL EMMET RYAN, a citizen of the United States, residing at Fall River, county of Bristol, Commonwcalth of Massachusetts, have invented certain new and useful Improvements in Combined Shaving and Clipping Machines, ofwhich the following is a specification.

This invention relates to shaving machines and particularly to a machine for shaving the tips and .certain hairs of the fur growths of skins.

This present invention contemplates certain attachments for and improvements upon the shaving machine of a prior patent granted to me April 23, 1912, No.

1,024,149, to which reference is made as illustrating the general type of machine involved herein and as giving a full and clear discussion of the conditions and practice in the art to which this invention is appropriated.

My present invention while embodying much of the structure of my prior machine and While having many of the objects of that machine generally in view, in the main contemplates the provision of means for securing either a shaving or a clipping action of that machine. In the preparation of some skins and more particularly in the treatment of certain hairs of some skins, it is necessary to positively clip these hairs between two cutting edges as distinguished from shaving them by bringing them past a single cutting edge. To the end therefore of providing an attachment for a shaving machine of the class described, which will enable the machine to be used either as a shaving machine or a clipping machine, I have devised my present invention. In this invention I adjustably support a clipper device in the path of feed of the skin and in coactive relation to the shaving blades. The clipper may consist of a simple knife set at a proper angle and capable of a fine adjustment relative to the shaving blades by a set screw. The knife is adjustable into and out of the path of the feed of the skin by a support slidably mounted on the table of the machine. This permits the knife attachment to be moved out of the way when it is desired to use the machine solely as a shaving machine. In using the machine as a shaving machine, the supporting bar for'the skin is lowered to position the skin ineffective relation to rection of rotation so as to a rest roll disposed below and in periph- In the drawings forming a part of that" specification I have shown as an illustratedembodiment a form of machine which has been found satisfactory in use and well adapted to the requirements of" manufacture.

Throughout specification and drawings like reference numerals are correspondingly applied, and in these drawings:

Figure 1 is a vertical section of a shaving machine equipped with my attachment, and Fig. 2 is a front view of the machine.

I have indicated at 1 asuitably supported bed or table from which rise suitable bearmgs 2. Suitably journaled in the bean ings 2 is a cutter shaft 3 and a roll shaft 4. The cutter shaft 3 has a shell 5 fixed thereto and the roll shaft has a roll 6 preferably of .rubber and usually of smaller diameter than the peripheral measurement of the cutters 7 carried by the shell 5. The cutters 7 are preferably spirally disposed on the shell 5 and are set forward in their digive a slightly curved forward surface.

The cutter shaft 3 is driven by a large pulley 8 and the roll shaft 4 is driven in the opposite direction by a smaller pulley 9 so that the roll 6 will revolve faster than the cutters 7.

The end of the cutter shaft 3 is journaled in a box 10 adjustably mounted in a support 11 at the end of the bed 1 and held therein by a set screw .12. The journal boxes for the cutter shaft 3 are vertically adjustable by means of set screws 13 and the journal boxes for the roll shaft 4 are diagonally adjustable by set screws 14.

Thetable 1 between the spaced bearings 2 is recessed to receive a bed plate 15 to which is adjustably fastened by the bolts 16 and slots 17 the base 18 of a knife support 19. The adjustment of the knife support 19 'is' toward and from the knife shaft 3 and and bolt connections 22 The adjustment of the knife 22 toward and from the cutters 7 is held by a set screw 23 set up ir a lug 23 rising from the slideway for the knife.

Secured to the under face of the table 1 is a pair of spaced guides 24 providing a slideway for a slide 25. The slide 25 is provided with a pair of spaced adjustable arms 26 between the ends of which is a guide bar 27. The guide bar 27 is adjustably held by a thumb nut 28 so that its position can be changed according to the nature of the skin S which is being drawnover it. The adjustment of the supporting arms 26 is held by set screws 29.

The slide 25 is normally held out away from the table 1 by springs 30 set on suitably supported rods 31. The slide is advanced to the blades 7 by the pressure of the body of the operative against the slide while at the same time he draws the skin over the guide bar 27 by taking hold of the skin with one hand at each end.

The skins operated upon in this machine are usually of double layer, as shown. The growth f indicated in the lighter lines represents the fiber growth of slightly varying length. The darker growth indicated at it indicates the master hairs which are to be shaved. The fibers f are rooted in the outer skin, while the master hairs are rooted in the inner skin.

As the skin is drawn down across the guide bar 27 the natural growth of the hair.

is inclined forward in the direction of movement of" the skin and the cutters 7 strike down toward the fur growth swinging in the direction of that growth and therefore stroking with the growth of hair. This shingles the master hairs which are to be slipped directly over the knife 22 and directlyover the lower fiber f which is to be rotected against the action of the cutters.

he knife 22 therefore supports and presents the hairs to be out directly into the path of the cutters 7 and between said cutters and its own sharpened edge so that the hair is straightened out in its normal direction and arranged so as to present the tips of the longest growth at the line of shaving knife 22.

The position of the knife 22 may be roughly determined by adjustment of the support 19 on the bed plate 15. The fine adjustment of the knife relative to the cutters and to the line of presentation of the skin is had through the set screw 23. Where it is not desired to use the machine as a clipping machine, the clipping attachmentmay be moved back out of line of presentation of the skin by loosening the set screw and slid- -ments therefore enable the machine to be used either as a shaving machine, in which case the cutting action takes place between the rotary cutter 7 and the rest roll 6, or as a clipping machine, in which case the cutting action takes place between the rotary cutter and the knife 22.

Various modifications in the construction and operation of my device may obviously be resorted to Without departing from the spirit of my invention if within the limits of the appended claims.

What I therefore claim and desire to secure by Letters Patent is:

1. In a machine of the class described, a rotary cutter, a rest member efiectively disposed relative thereto, a shear blade disposed in coactive relation to said rotary cutter, and an adjustable support for an article to be clipped having an effective position wherein the article is presented between said rotary cutter and shear blade and having' an adjusted position wherein the article is presented between said rotary cutter and said rest member.

2. In a machine of the class described, a rotary cutter, a rest roll in operative relation thereto, a shear blade mounted in vertically and horizontally adjustable relation to said cutter, and an adjustable work holder having an effective position wherein the work carried thereby is presented for clipping between the rotary cutter and the shear blade, and having an adjusted position wherein the work is presented for clipping between the rotary cutter and the rest roll.

3. In a machine of the class described, a rotary cutter, a rest roll below and in peripheral contact therewith, a shear blade movable into and out of operative relation to saidcutter, and an adjustable work holder having an effective position wherein the work carried thereby is presented for clipping between the rotary cutter and the shear between the cutters 7 and the edgeof the blade, and having an adjusted position secured by moving the shear blade out of operative relation to the rotary cutter and wherein the work is presented for clipping between the rotary cutter and the rest roll.

In testimony whereof I aflix my signature in presence of two witnesses.
